Late
TL;DR
Late (now Zernio) is a developer-first social media scheduling API that posts, schedules, and analyzes content across Instagram, TikTok, LinkedIn, YouTube, Facebook, and more from a single request or a no-code dashboard.
Key Facts

Additional Pricing Information
The AppSumo deal sold the old 'Late' product as 4 one-time lifetime tiers. The vendor has since rebranded to Zernio and moved to a per-connected-account subscription model on its own site (first 2 accounts free, then $6/$3/$1 per account per month), so the one-time tiers only exist through the AppSumo deal. X (Twitter) posting requires a separate bring-your-own-key (BYOK) add-on with a one-time $49 setup fee.
Details
What is Late?
Late (now rebranded to Zernio) is a developer-first social media scheduling platform: a single REST API endpoint plus a no-code dashboard that posts and schedules content across Instagram, TikTok, LinkedIn, Facebook, YouTube, Threads, and — since a 2025 update — Reddit, Pinterest, and Bluesky. Instead of building and maintaining separate integrations for every network's SDK, developers can publish with one request; non-developers can use the visual dashboard with a calendar, media preview, bulk CSV scheduling, and per-profile filters. It supports images, videos, reels, carousels, and text, with uploads up to 5 GB, full thread scheduling for X and Threads, YouTube tags/thumbnails/first comments, Instagram collaborators, and team features like per-profile invites and shareable connect URLs. The tool claims 99.97% uptime and 2.3M+ posts delivered. The AppSumo deal (4.0/5, 84 reviews) sold lifetime access in four one-time tiers from $49 to $399, but that deal is now sold out — the vendor's own site has moved to a usage-based model charging per connected social account ($6/$3/$1 per account per month after the first 2 free). The founder, Miquel Palet, runs the product out of Girona, Spain as a small bootstrapped team, which makes the platform's breadth and the 16-integration roadmap both its appeal and its main longevity risk.
Key Features
- *Unified Scheduling API** — Post or schedule text, images, and video to Instagram, TikTok, LinkedIn, Facebook, YouTube, Threads, and more with one REST request instead of juggling platform-specific SDKs.
- *No-Code Dashboard** — Compose and schedule posts visually with a calendar view, media preview, auto-expanding composer, and profile/date filters — no coding required.
- *Multi-Account Management** — Connect up to 300 accounts (250 profiles on the top tier) across brands and clients without switching logins.
- *Bulk CSV Scheduling** — Upload dozens of posts in a CSV, set a date and time per row, and schedule them all at once.
- *Thread Scheduling** — Compose and schedule entire multi-post threads for X and Threads from the dashboard or the API.
- *Rich Media Publishing** — Post images, videos, reels, carousels, and text-only content, with uploads up to 5 GB and YouTube tags, thumbnails, and first comments.
- *Team Collaboration** — Invite teammates with per-profile access, clone connections for fast onboarding, and shareable connect URLs so clients can link accounts without logging in.
- *No-Code Integrations** — Trigger posting through Zapier, n8n, or Make without writing custom code, plus an AI assistant in the docs for API questions.
- *Reliability & Monitoring** — 99.97% uptime, 2.3M+ posts delivered, and email alerts for failed scheduled posts so you can fix issues fast.
Who is it for?
- Developers and SaaS builders who want one API instead of maintaining separate integrations for every social platform
- Agencies managing dozens of client accounts and profiles who need multi-account control and per-profile permissions in one dashboard
- Social media managers who want a code-free scheduling dashboard with a calendar, threads, and bulk uploads
- Content teams scheduling reels, carousels, and video across several networks at once
- Automation tinkerers building publishing flows in n8n, Make, or Zapier
Who is it NOT for?
- X/Twitter-heavy teams — X posting requires a separate BYOK add-on with a $49 setup fee after the August 2025 change
- Solo users managing one or two channels who just need simple scheduling — Buffer or Later are easier and cheaper
- Enterprises that need deep social listening, inbox management, or CRM-level engagement features beyond publishing
- Buyers who need a proven, long-track-record vendor with independent reviews — there's no TrustRadius or G2 listing to lean on
- Anyone shopping the one-time lifetime deal right now — it's sold out on AppSumo and the vendor only sells per-account subscriptions today
The Bottom Line
Late's core idea is genuinely good — one API and one dashboard for publishing across every major network is exactly the kind of tool developers and agencies keep re-building by hand. The 4.0/5 from 84 AppSumo buyers and the founder's very public shipping cadence suggest the product works. But the timing is brutal: the AppSumo lifetime deal is sold out, the product has already rebranded to Zernio and moved to per-account subscriptions, and X posting got pulled and turned into a paid add-on within months. If you own one of the sold-out lifetime tiers, you got a real deal and should ride it out — but new buyers are paying a young bootstrapped team per-account forever, with no independent reviews and a platform whose costs depend entirely on networks like X and Meta that keep raising API prices. That's a tough pass unless you're a developer who specifically needs the unified API and can live with the longevity risk.
